(3S,4R)-1-tert-Butyl 3-methyl 4-(6-Bromo-5-pival-amidopyridin-3-yl)pyrrolidine-1,3-dicarboxylate CAS 1420780-27-3 chemical structure

Description

The occurrence of (3S,4R)-1-tert-Butyl 3-methyl 4-(6-Bromo-5-pival-amidopyridin-3-yl)pyrrolidine-1,3-dicarboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3S,4R)-1-tert-Butyl 3-methyl 4-(6-Bromo-5-pival-amidopyridin-3-yl)pyrrolidine-1,3-dicarboxylate (CAS 1420780-27-3), molecular formula C21H30BrN3O5 and molecular weight 484.38 g/mol, is a CATO reference standard with documented purity and traceability.

(3S,4R)-1-tert-Butyl 3-methyl 4-(6-Bromo-5-pival-amidopyridin-3-yl)pyrrolidine-1,3-dicarboxylate (C21H30BrN3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (3S,4R)-1-tert-Butyl 3-methyl 4-(6-Bromo-5-pival-amidopyridin-3-yl)pyrrolidine-1,3-dicarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
